IMPROVEMENT IN MACHINES FR T ISTING AND PLAITING CORUS.

Specification forming part of Letters Patent No. 42,613, dated May 3,1864.

To all whom it may concern:

Be it known that I, J. T. VILLIAMS, of Newark, in the county of Essexand State of New Jersey, have invented a new and useful Improvement inMachinery for Twisting and .Plaiting Cords; and I do hereby declare thatthe following is a full, clear, and exact description of the saine,reference being had to the accompanying drawings, forming a part of thisspecification, in which- Figure l represents a planor top view of myinvention. Fig. 2 is a longitudinal vertical section of the same.

Similar letters of reference in both views indicate corresponding parts.

In covering or plaiting cords the quality of the work with ordinarymachines depends entirely upon the skill of the workman. The cord to becovered is secured to two hooks, and while a quick rotary motion isimparted to the same the plaitin g material is applied by hand. Thedistribution of the covering or plaiting depends entirely upon therelative speed with which the plaiting-threads, whether in the hands ofa workman or attached to machinery, move along. If they move quick thecovering becomes thin. 1f they move slow a large quantity of the sameaccumulates in one spot, and the covering becomes thick. An evendistribution of the plaiting-threads therefore can be insured only byinsuring a uniform speed as the same are carried along eon the strand orcord to be covered.

To effect this purpose by simple and reliable means is the principalobject of this invention, which consists in the employment or use of anendless belt, arranged alongside the twisting-hooks in such a mannerthat the speed of the plaiting-thread as it moves along .on the strandor cord is regulated by the speed of said belt, which derives its motionfrom the same shaft which also transmits mo tion to the cord.

This invention also relates to the use of an endless belt for pullingout and laying the required length of strand previous to the twistingoperation and to the arrangement of hooks on said belt for the purposeof holding the inished cord while the same is being wound upon thespool.

To enable those skilled in the art to make and use my invention, I willproceed to describe it.

A represents a frame, made of wood or any other suitable material, ofvsuliicient strength to form the bearings for the driving shalt B. Thisshaft bears a large pulley, C, from which a belt extends round a seriesof pulleys, D, on the inner ends ofthe twisting-hooks E, one only beingshown in the drawings. The speed of the twisting-hooks therefore dependsdirectly upon the speed of the driving-shaft. F is a cone-pulley securedto the driving-shaft B, and a belt extending from this cone-pulley overa similar pulley, G, serves to impart motion to a shaft, H, which hasits bearings in the upper part of the frame A. The shaft H extendsbeyond said frame, and mounted on its end is the cone-drum I, from whichan endless belt, J, extends over a pulley, 7c, the shaft of which hasits bearings in a frame, L, capable of sliding backward and forward insuitable ways in such a manner that the tension of the said endless beltcan be regulated at pleasure. The ways L', which form the guides for theframe L, are situated at the opposite end of the room or at such adistance from the frame A as the length of the cords require.

The speed of the endless belt J therefore depends upon the speed of thedriving-shaft, and it will increase or decrease in the same ratio asthat of the twisting-hooks.

The cord to be plaited is attached to the twisting-hooks in the usualmanner, and the plait-ing-threads are applied by hand. In order toinsure an even distribution, the little finger of the hand is hookedover the belt, as shown in Fig. 2 of the drawings, and as the hand isthus carried along by the belt with a uniform speed the plaitingthreadsare evenly distributed over the surface of the cord. By varying thespeed of the endless belt J the quality of the work can be regulated.

The plaiting-threads may, however, be attached to a carrier fastened tothe belt J, and the whole work can thus be accomplished automatically.

The main or driving shaft is also connected by a belt or in any othersuitable manner with a shaft, M, which has a pulley on it carrying anendless belt, N, on which are one or more frames, O, to which arefastened the ends of the strand-threads. When the strand is drawn outthe required length, the threads are detached from the frame 0 by meansof a hook, a. The belt N extends over two pulleys, b c, the axles ofwhich have their bearings in a suitable frame, l), at the opposite endof the room or at the required distance from the frame A. In order tofacilitate the operation of detaehing the strand-threads from the hooka, said hook is attaehed to a block, d,Whieh is provided with trunnionsd', so that it can be turned back.

One or more hooks, e, are fastened to the belt N, and When a iinishedcord is removed from the twisting-hooks one end is fastened to theWindingspool and the other to one of the hooks e, which holds it as itis being wound.

The belt N is intended to run alongside the oord to be plaited, and askillful Workman may gage the speed with which he applies theplanting-threads by observing; and following the speed of the belt N.

tion of the Covering or plaiting material.

2. The use of an endless belt, N, with frames 0, or their equivalents,as described, for the vpurpose of pulling out and laying the requiredlength of strand previous to the twisting operation.

3. The application of hooks e, or their equivalents, to the laying-beltN, as and for the purpose set forth.
